This inventionrelates to'iinproveinents in ventilatorsV and has for itsobject to provide a ventilator which, may be readily attachedfto the roof of,v a passenger car orto any enclosed chamber to be'ventilated. `My improved yen tilator is constructedninsuch wise as to pro# duce an efiicienteahaust of airlfrom thespace being ventilated andsoas to preventtheentrance of bac-li drafts,V moisture, dirt7 cinders or'the like into such-spiace. Another advantage resides in ltlie ability -to manufacture my ventilatorat lrelatively low cost. 1' This'and other. objects and advantages will be vmore fully set forth and described in the following speciication and shown the accompanying drawings in' which, Y "j y j Fig. l'isafplan viewof a passengerica'r showing'lniy ventilators'attached to the clearstorythereof; i i

To effect this method of attachment, I providewhat is termed an adapter or coupler-generally indi- ,cated by numeral `15 which` comprises a casing having the inlet port 15EL around which extends the inclined attachment collar 15b which is suitably a'pertured for attachmentto the inclined deckof the car by means of bolts, screws or thelike., The adapter is provided with a plane front wall 15C having the aper-y ture 15d therein. Supporting lugs 15e pro- Y ject fromthe sides into thel opening 15d. A

flange 15 extends around three sides of they opening 15d and is suitably apertured atlg to permit insertion of fastening screws f vthrough the` fiange; 15t and into the corre spending apertures inthe fiange-11c of the Vventilator 11. rIihe latter ismounted as indicated inv dotted lines in Fig.,5 with its neck '11F projecting into the opening 15d, and rest-y ing upon the lugs 15?, andv is securediin place by suitable fastening screws as indicated above.' rThe function is similar to that de`l scribed above save that theexhaust air is drawn out or passes outy through aperture l7151 before it reaches the ventilator311;` kIn Fig. 7 I have shown another modified form in which lthe end walls 11? of the upper or curved l roof portion ofthe ventilator vconverge from theclearstory outwardly. Similarlythe end walls 11y of thelower portion of the ventilator are alsoconvergently arranged but with aL lesserv degree of inclination, although such inclination maybe varied'asto bothparts of the ventilator to meet conditions land require- .ments In the form shown in 7 a differencein the angle of convergence of the walls' lplandflly necessitates provision of an out- .wardly inclined"connectingy web l1? 4as* shown inFig. 7. The construction and operation of thisA forrnf of my ventilator is substantially .a similar to .that 'of the forni previously described save that the Aairr impingingupon the end walls of the ventilator does not encounter the same ina relatively 'perpendicular directionbut at an angle so thatthe resistance is lessand thereisy'anadded rfc-direction of the air glancing off the endy walls 11X and the connectingwebs 11Z over the upper end of the exhaust passage 11i. n

In Figs; 8 toll I have illustrated still another yformo'f my inventionY in which the construction isgenerally"similar*` to that of the form of Figs. 1 to 4 save that the front and rear walls 11h and 11F1r respectively are pro vided with the vertical ribs 11r which are provided with V-shaped seats orgrooves 11S. A centralpartition 11m is Yretained cast integral'with the body of theY ventilator but the other partitions 11t are formed of light sheet metal as copper .with the ends'llw rearwardly bent or inclined to permit seating in the grooves 11T, preferably so that some force is requiredfor insertion or removal toensure retention in proper position and toprevent ratt-ling'. In this form the partition sheets 11t are provided with upper'and lowerv outwardly struck tongues 111,11W respectively, forming longitudinal ports or apertures 110 in the sheets. Back currents making their way into kthe spaces between the partitions 11t will encounter these .tongues 11", 111, affording a resistance from further passage and eddying or baffling them. At the saine time it is believed that these tongues constricting as they do the passage between Athe partitions enhances the eduction V action. `In thisr forin the bottom plate y111 is also formed of light sheet metal with its front and rear edges 111a reversely bent. The platey is preferably attached by fastening screws 112 extending through the plate into suitable apertured fastening bosses 113 formed integral with the front and side walls of the ventilator 11. y Y

Save as stated above the function of this ventilator is generallysimilar to that shown in Figs. y1 to 3 describedabove. s.

Itwill be obvious .that my inventionis susceptible to other modifications and I do not wish to be restricted to the form shown' and vdescribed save as defined inthe appended claims.

VVhatI claim is: .y i f n 1. A ventilator having an entrance port in one plane, exhaust outlets'with an outlet passage extending therebetween, said outletsbeing in planes angularly disposed with respect entrance port and said outlet passage, and vertical partitions substantially parallel .to the ends-,of said ventilator located in. said first passage and extendingk the distance between said outlet-s. y j .4' Y

2. A'ventilator having an entrance port in one plane, exhaust outlets with an outlet passage extending therebetween, said outlets bef ingin planes angularly disposed. withy respect to the plane of said entranceport, and a passage extending'A between and connecting said entrance port and saidy firstnamed passage,` and vertical partitions located in said `outlet 115 to the plane of said entrance'port anda pasl jsage extendingv between and connecting 'said passage and extending upwardly into said second passage..

3. A ventilator provided with front, rear and side walls, a downwardly and outwardly directed top wall extending between lsaidside walls, said ventilator being open between said top wall and saidfrontwall to form a dis charge opening said rear wall boing extended beyond the limits of said front wall and hav ingL an inlet port above said discharge opening. j

4. A ventilator comprising a casing formed with end walls, a front wall, a rear wall and a top wall, said casing being provided with a discharge opening adjacent the upper portion of said front wall and being further provided with an entrance port in the rear wallv located above the discharge opening and olfset with respect to said discharge opening. A ventilator comprising a casing formed with front,'rear alid end walls and a top wall, said casing being further provided with a dis'- charge opening adjacent the upper portion of the front wall and an entrance port in the rear wall above the level of said discharge open`` discharge opening adjacent the upper portion of the front wall and an entrance port in the Y rear wall above the level of said discharge opening, said casing being further provided` into the space beneath saidy with a bot-tom wall extending outwardly from the rearwall, and partitions ext-ending from said front to said rear wall, said partitions being reni'ovablyinounted in said "casing,`

8. A ventilator comprising a casing with side, top, front and rear walls, said front and rear walls being provided with grooves, partition platesextending between and seated in j said grooves, said partitions being provided with reversely bent edge portions` located in said groov s;

9.A A ventilatorcomprising a casing havingv an entrance port and a discharge opening,

said ventilator being provided with a connecting passagebetweensaid port and opening and being further provided with means attachable to the clearstory of a car or the like,

and an ladapter comprising a conduit, said adapter being attacliable to the deck of a car and detachably engageable by said ventilator to aline said port with said conduit.
